Definitions

  • the present invention relates to a device for the palate extension with a in its length dimension extendable and / or shortenable extension part, the both ends have a fixing part.
  • Such a device also referred to as a distractor, is an orthodontic surgical device Apparatus that allows gradual, i.e. gradual extension rapidly expand the upper jaw in width or gradually add two other bone segments, in the sense of a distraction to move apart.
  • the apparatus can also an enlargement of the upper jaw can be used in one step to determine the position of the to be able to precisely adjust both halves of the palate to each other and to the lower jaw. This can lead to occlusion disorders, malformations, bone asymmetries and mismatches between upper and lower jaw are corrected, which are congenital or acquired could be.
  • the first main application the so-called rapid palate expansion, works therefore, an insufficient width of the upper jaw due to an orthodontic orthodontic Correct treatment so that the relationship between maxillary and mandibular arch is normalized.
  • the upper jaw consists of a left and a right half, which are united in the mid-sagittal plane in the palate seam. In patients under the age of 12-14 years, this connection is generally still not ossified over a large area, so that the two are gradually separated Halves the orthognathic correction is easy to do. In older adolescents or adults, the seam has grown together to an increasing extent. In these cases, surgical support is often necessary by adding parts of the upper jaw are weakened so that the suture can be opened again, to then carry out the gradual widening.
  • the conventional distraction of bone segments in any direction it's about bone dimensions that are too small enlarge.
  • a typical example is the too short horizontal part of the lower jaw, the results in an overjet (overbite) with the associated orthodontic complications and the aesthetic problems with the face profile.
  • overjet overbite
  • a jaw surgery The bone is severed and bridged by the distractor. After a short healing period of a few days, this becomes the separation point bridging healing tissue, the callus, gradually distracts, i.e. the bone compartments moved apart by means of the distractor.
  • such devices are only used intraoperatively to position to be able to precisely adjust parts of the upper jaw against each other, e.g. in the case a cleft lip and palate. This attitude is very much without such help difficult because of the tensile forces exerted by the soft parts.
  • the desired one After checking the occlusion with the lower jaw, the bone parts become position screwed in the position achieved and the device is then again away.
  • WO 94/10933 describes a distractor that can be found both on teeth and also supported on palate plates.
  • a disadvantage of periodontal support is also that the two halves of the palate can tilt in the existing supports in the frontal plane instead of to move apart in a stable angular position in the frontal view.
  • the present invention has for its object to provide a distractor that the above-mentioned disadvantages of known distractors, especially those that leaning on the tooth, at least partially avoiding it.
  • a device for the palate extension with an in its length dimension extendable and / or shortenable extension part that its two ends each have a fixing part, which is characterized in that each fixing part is constructed as a punctiform bone support part.
  • Such a distractor avoids palate plates or supports on the teeth that have the disadvantages indicated above by the expansion part over the Bone fixation parts and support punctiform.
  • a stab incision in the palate mucosa either screwed special anchoring screws into the bone or the support parts are designed as a mandrel.
  • Such support parts can be placed on the bone practically at any position and thus fixed, regardless of the position of the teeth, which in no way as Retaining means for such extension parts are needed.
  • there are no special adjustments be made for each patient such as this is the case with palate plates or teeth.
  • the device axes can be placed so that not only an enlargement of the palate, but at the same time an extension, if this is necessary.
  • the bone support part can be connected to the extension part via a adjustable joint that can be fixed in its position; with this connection A moment can be transmitted between the extension part and the bone support / screw if necessary, by in one variant the joint on the fastening unit is clamped, while in another variant it is rigid.
  • Such thickenings which in a further embodiment are plate-like or bead-like have the additional advantage that they grow into the mucous membrane can, so that there is a positive connection.
  • this ingrowth has Advantage that the bone support part is held in position and does not fall off can.
  • extension part there are at least three threaded elements for this provided that screwed together two opposing pairs of threads form, with a rotation of the central threaded element in one or the extended or shortened the extension part in the other direction of rotation.
  • Such extension parts can be easily extended or shortened despite their simple structure; the Amount of an extension or a shortening per revolution of the thread can be about be specified by the thread pitch.
  • the extension part is made of at least three elements. These three elements are interconnected, the the first element is sleeve-shaped and rotatably supported therein the second element records. The third element is screwed to the second element so that under Rotation of the second element in one direction or in the other direction the third element is pulled into or pushed out of the first element and thus the extension part is shortened or lengthened.
  • the respective clamping part on the extension part can be released and are slidably disposed so that the bone support member held therein can be moved together with this clamping part.
  • the clamping part on the extension part is also detachable and slidably arranged.
  • one Pressure area is provided, on which a corresponding tool is attached.
  • Such one Tool can be a pair of pliers between the two opposite one another Pressure surfaces of the two bone support parts are inserted and spread, so that the bone support parts are shifted towards the bone.
  • a rough setting can be made to to position the distractor while the fine drive then extends over the Threaded rods is made.
  • Such a pressure surface on the bone support part can be formed as a depression, so that a corresponding slipping off tool attached to it is prevented.
  • the joint with which the respective bone support part on the extension part is preferred is connected to be formed by a ball joint, the ball of the joint is assigned to the bone support part, while the extension part has a corresponding one Ball socket for receiving this ball and for clamping and holding the Ball.
  • a ball joint which is either held or rotatable can be jammed in the bearing pan, allows adjustment of the distractor so that the bone support elements do not only move apart linearly.
  • the ball head can be a variant between the bony support and the extension part not be tightened or temporarily loosened, which then Allow the bone segments to adjust their angle to each other easily and thus, for example the TMJ heads in the midline distraction of the lower jaw in the Pan remain, so there are no problems in the patient's temporomandibular joints occur.
  • the clamping parts mentioned above can be designed so that they each have a threaded element of the extension part.
  • the respective threaded element of the Clamping part be a sleeve with an internal thread, into which there is a corresponding threaded rod screwed in.

  • the use of the distractor 1, as also shown in FIG Figures 1a and 1b is shown in an oblique arrangement in the palate to a Asymmetry of the alveolar process AF of the upper jaw, for example as a result of a cleft lip and palate (also called Hasenscharte) to compensate and the deformed Part of the alveolar process immediately against the pull of the soft parts in the correct position bring to.
  • the distraction is continued until the bone parts are in the correct position Occlusion are aligned; afterwards the bone parts can be reached in the Position screwed together by means of suitable plates or screw elements, which are not shown become.
  • FIG. 3 shows the use of a single distractor around a front segment, designated FS. to gradually move the upper jaw forward, for example by an imbalance to balance between the upper and lower teeth or by one resolve so-called frontal crowding, in which the teeth twist due to lack of space or nested.
